The Olet is mainly used for the reinforcement type pipe fittings of branch connection.The body is made of high-quality forgings with the same material as the pipe, including carbon steel, alloy steel, stainless steel, etc. The Olet and the main pipe are welded. There are three types of connection with the Olet or other pipes, instruments and valves: butt welding, socket welding and threaded connection. The pipe on which the branch is connected is called the main pipe, and the pipe on which the branch is connected is called the Olet. The base of the threaded Olet is the same as the butt welding Olet, but its branch connection adopts threaded connection and does not need welding. Butt welding Olet is the most common branch connector. Its end is beveled and connected with straight pipe by butt welding, so it is considered as a butt welding pipe piece.
The base of Olet is the same as that of butt welding branch, but its branch connection adopts socket welding connection.

Others: Miter branch is used for 45 ° branch. Butt welding, socket welding and threaded connection can be used for connection with Olet. Elbow branch tables are used to provide branch connections on long radius elbows or short radius elbows. Butt welding, socket welding and threaded connection can be adopted for the connection of elbow Olet. The shape of embedded socket is wavy, and it is reinforced as a whole. It is butt welded with Olet and is commonly used in low-pressure pipeline.
